HANDLE ATTACHMENT FOR PLANES.

SPECIFICATION forming part of Letters Patent No. 337,581, dated March 9,1886. Application filed October 1, 1885. Serial No. 178,684. (No modelTo all whom it may concern:

Be it known that 1, ROBERT T. HENDRICK- soN, a citizen of the UnitedStates, residing at Brooklyn, county of Kings, State of New York, haveinvented a certain new and Improved Handle Attachment for WoodPlanes, ofwhich the following is a specification.

The operation of planing floors, &c.,by means of the ordinary hand-planeis both tedious and trying to the workman, by reason of the awkward andunnatural positions he is compelled to assume in performing this work,which is probably the hardest of all manual labors.

Now, this invention has for its object to facilitate the labor ofplaning floors, &c., and to provide a means by which said work may bedone without obliging the operator to assume other than a naturalstanding position; and it consists of a handle pivoted to a frame-pieceadapted to be attached to any ordinary woodplane, said handle beingsufficiently long to be grasped by the operator while standing, when theplane is resting on the floor, leaving him free to exercise the whole ofhis strength in a natural manner in pushing the plane over the floor,thus enabling much more work to be accomplished in a given time and withless exertion than can now be done by using the plane in the ordinarymanner.

In the accompanying drawings, forming part of this specification, Figurel is a perspective view of a hand-plane with my improved handleattachment applied thereto. Fig. 2 is an end view of the same, and Fig.3 is a side view of a modification in the construction.

The wood-plane a is of the ordinary construction, and my improved handleattachment is composed of two side frames, 5 b, secured by screws to theside of the plane and having up wardly-projecting ears or lugs b bbetween which the handle is pivoted. The side frames, b b, are so formedthat the pivotal centers of the handle are above the top of the planeand vertically situated between the cutting-edge of the plane-iron a andthe heel a of the plane.

The handle comprises a bifurcated piece. 0, having a socket, the shafta, secured in said socket, and the cross hand-piece 0 secured on theupper end of the shaft 0. The bifurcated piece a is connected to theears b b of the side frames, b b, by the bolt d, which passes throughthem and is held in place by the nut d.

The handle-shaft c is sufficientlylong to allow the operator to use theplane while standing by pushing it forward on the floor, thus placinghim in the most convenient and easy position to apply his strengtheconomically and without undue fatigue to accomplish Work which nowcalls for extra exertion, as the manual planing of floors by means ofthe common hand plane in the ordinary manner is one of the most arduousduties performed by mechanics.

The cross handpiece 0 is preferably made sufficiently long to beconveniently grasped by both hands, the pressure being applied in adownward forward direction, and, by reason of the position of thepivoted connection in the ears I) If relatively to the working-face ofthe plane, the operator has perfect control over the plane and candivide the pressing force between the cuttingedge and the heel of theplane, as desired, by varying the angle at which the handle is held, andas the upper end of the handle has to be moved a considerable distancerelatively to the plane to cause slight variations in the position ofthecenter of pressure between the cuttingedge and the heel, the rightamount of force to cause the plane-iron to grip and to drive the planeforward can be applied by the operator to a'nicety.

This handle attachment can be applied to planes of different widths byplacing washers ee between the bifurcated piece 0 and ears 1) b so as tobring the handle central with the plane, as shown at Fig. 2.

In applying this attachment to planes for use on hard woods it may beadvantageous to connect the pivoted handle so as to yield slightlyagainst the pressure, instead of connecting it rigidly to the plane.This may be done by making the upwardly-projecting ears I) bsufficiently light to act as springs; or the construction shown in Fig.3 maybe adopted, in which the piece 0 of the handle is pivoted at eachside to the end of a bar, f, which is connected at its other end to aspring, secured to the side frame, the upper end of the bar f being heldin an opening formed through the ear b.

It will be readily seen that planes, by the employment of this handleattachment, may be easily used in places which cannot be reached by theplane alone.

Having now described my invention,what I claim, and desire to secure byLetters Patent, wardly-projecting ears b 1), extending above 15 istheplane and vertically situated between the 1.
